I tried to update my packages using update.packages()

I got the following message:

The downloaded packages are in
        ‘/tmp/RtmpyDYdTX/downloaded_packages’
Warning in install.packages(update[instlib == l, "Package"], l, contriburl =
contriburl,  :
   'lib = "/usr/lib/R/library"' is not writable
Error in install.packages(update[instlib == l, "Package"], l, contriburl =
contriburl,  :
   unable to install package

How do I fix this ?

If you want to update packages in R's default library in /usr/lib/R/library, you will need root permissions.
